I can do SELECT and WHERE. My joins give me way too many rows and I do not know which ones are wrong.

CLAUDE · WITH THIS SKILL You get: a short task, list every customer with the total value of their paid orders, including customers who never ordered -> your query uses a LEFT JOIN with WHERE o.status = 'paid' -> the count comes back at 210 customers instead of 900 -> instead of a rewrite, the question, for a customer with no orders at all, what value does o.status hold on that row -> you answer NULL -> then the follow up, does NULL equal 'paid' -> you see the WHERE deleted the very rows the LEFT JOIN kept -> the concept named, a filter on the right table turns a LEFT JOIN into an inner one, and the fix belongs in the ON clause -> a progress block for next time.

// what's inside

這項技能包含什麼

Clause execution order taught first, because it explains most SQL bugs
LEFT JOIN, NULL behaviour and join fan out drilled until they are boring
Wrong row counts turned into questions you diagnose yourself
Dialect checked up front: Postgres, MySQL, SQL Server, SQLite or BigQuery

Analysts who inherited a database, marketers tired of asking someone else for a pull, developers who copy queries without reading them, and anyone facing a SQL screen at interview.

// what's inside

What you're actually buying

這位 AI SQL 導師適合那些會寫包含 WHERE 的 SELECT，卻不太會其他內容的人。接著一個 JOIN 讓 400 筆訂單變成 1,200 筆，LEFT JOIN 悄悄捨棄了你正在尋找的客戶，而你說不出原因。這個檔案會將 Claude、ChatGPT 或 Gemini 變成一位導師，讓你親自撰寫查詢並讀懂自己的資料列數，而不是直接查看別人寫好的解答。

它會先讓你使用一個你描述的結構描述執行查詢，接著教你大多數課程會跳過的重點：資料庫實際執行各個子句的順序，也就是 FROM、WHERE、GROUP BY、HAVING，最後才是 SELECT。這一點就能消除一半的 SQL 困惑。在此基礎上，它會帶你學習 JOIN、資料列倍增、NULL 行為、CTE 和視窗函數。當你的結果集大小不對時，它不會直接重寫查詢，而是詢問你預期有多少筆資料，以及多出的資料列是從哪裡來的。

一個檔案，在 Claude、ChatGPT 和 Gemini 中都完全相同。將它貼到 Project、自訂 GPT 或 Gem 中，大約兩分鐘就能設定完成，而且永久屬於你，不需要訂閱。

## Who you are
You are a Socratic SQL tutor. Your job is to make the learner able to write a query against an unfamiliar schema and defend its row count. You are not a query generator.

Tone: plain, calm, specific. Short sentences. One idea per turn.

The one rule: you never write the finished query for a task you have set. You can show the same clause on another table, ask a question, or name the concept. You cannot hand over the answer.

## What you know about SQL
- The learnable order: SELECT and WHERE, logical execution order, filtering and NULL, aggregates with GROUP BY, INNER JOIN, LEFT JOIN, join fan out, subqueries and CTEs, window functions, then indexes and safe

關於此產品的問題

How does this SQL tutor work if I do not have a database yet?+

It gives you a small schema in text, three or four tables with a few rows each, and you write queries against it in the chat. If you would rather run them for real it tells you how to set up SQLite or a free Postgres instance in a few minutes. Once you have your own tables, you describe them and it teaches on those instead.

Will it just write the query for me?+

No. It is instructed never to write the finished query for a task it set you. When you are stuck it shows the same clause on a different table, or asks how many rows you expected and where the extras came from. Asking it to explain a query someone else wrote is a separate request and it will walk that line by line.

Which dialect does it teach, and does it cover window functions?+

It asks whether you are on PostgreSQL, MySQL, SQL Server, SQLite or BigQuery before it teaches anything with a date function or a string function, because those differ. Window functions are lesson nine: ROW_NUMBER, RANK, running totals and PARTITION BY, which is what most analyst interviews test.

Do I have to read it myself?+

No. The file is written for your AI to read, not for you. Upload it or paste it in once and the AI takes on the role. After that you just ask it questions the way you normally would. You're welcome to open it and read it, but nothing here depends on you doing that.

Is this a physical book?+

No, it's digital. You download it the moment the order goes through and it's yours permanently. The cover is styled like a book because each edition is written and edited as one self-contained piece of work. The reading part is your AI's job, not yours.
